superquadrics - morphing 3d shapes.

superquadrics [-display host:display.screen] [-visual visual] [-window] [-root] [-delay number] [-spinspeed number] [-count number] [-cycles number] [-wireframe] [-fps]

Ed Mackey reports that he wrote the first version of this program in BASIC on a Commodore 64 in 1987, as a 320x200 black and white wireframe. Now it is GL and has specular reflections.
